Abstract

The properties of an anharmonic chain are considered in the pseudoharmonic approximation. The dependence of the instability temperature on the arbitrary external tension is investigated. It is shown that the instability region of the linear chain is limited by the critical temperature and the critical tension.

Резюме

Исследуются свойства ангармонической линейной цепочки в псевдогармоническом приближении. Получена зависимость температуры неустойчивости от произвольного внешнего натяжения. Показано, что область неустойчивости линейной цепочки ограничена значениями критической температуры и критического натяжения.
